OLD BRIDGE - The Middlesex County Prosecutor's Office and the Old Bridge Police Department have announced that additional details have been confirmed in the investigation of the Pathmark shooting that left three dead.

Officials say they have confirmed that the gunman, Terence Tyler, had served in the U.S. Marines for four years before being honorably discharged in 2010 for medical reasons. Between June 2010 and November 2011, the 23-year-old gunman purchased three weapons: a shotgun, a .45-caliber handgun and a WASR-10, which is similar to an AK-47 assault weapon. In June of 2012, Tyler moved to Old Bridge, bringing the weapons with him, even though one of them is illegal to own in New Jersey.

Police and investigators say Tyler obtained the midnight to 8 a.m. shift at Pathmark on August 20, 2012, just 11 days before the shooting. On the day of the shooting, Tyler left the store at 3:30 a.m. with no discussion or known conflict with any of his coworkers.

On August 31, Tyler walked into the Pathmark located on Route 9 in Old Bridge and shot and killed two of his coworkers, Cristina LoBrutto and Bryan Breen, before turning the gun on himself.
